I'm on Debian Testing (currently still Wheezy) and there is an issue with desktop icons - nothing happens.

EDIT: I just noticed that my testing is now Jessie.

The icons are just launchers for command "steam steam://rungameid/GAMEID" so I've tried running this command in a terminal and this is what it says:

I've tried putting i386 glibc library from Ubuntu package to ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/. It didn't help.But according to this ( http://www.phoronix.com/scan.php?page=news_item&px=MTM2ODY ), Debian Jessie will come with with glibc 2.17 so I will wait for that.It will be the easiest way.

I run Steam for a long time on Debian 32 and 64 bit with the Ubuntu 2.15 libc. No issues.You just have to preload the libc like this (the folder can be arbitrary, just has to contain the libc libs (all libs from the ubuntu libc6 .deb in my case):
